针对军事领域中地理空间数据具有更高的敏感性、机密性的特点,对传统的基于角色的访问控制与强制访问控制结合后进行空间扩展,提出了一种基于角色的空间信息强制访问控制模型(spatial vector data rolebased mandatory access control,SV_RBMAC),在RBMAC模型的形式化描述和安全性定理基础上提出了此模型运用在空间矢量数据的操作模式,满足军事环境中重要信息系统的访问控制需求,在实现细粒度访问控制的同时,保障了空间数据的安全性。经实际原型系统实验证明具有较高的实用性。
【英文摘要】
Geospatial data for the military field has a higher sensitivity,confidentiality characteristic. This paper brought the spatial expansion of the model after combining the traditional mandatory access control model with role-based access control model,proposed a SV_RBMAC model. Based on formal description and security theorem of RBMAC model,it introduced the operating mechanism of SV_RBMAC model. The SV_RBMAC model has achieved good results in the implementation of the practical application. It turns out that...
